JOHN F. CHASE, OF AUGUSTA, MAINE.

CONDENSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 396,539, dated January 22, 1889.

Application filed October 31, 1888. Serial No. 289,646. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN F. CHASE, a citizen of the United States, residing at Augusta, in the county of Kenn ebec and State of Maine, have invented certain new and useful Improvement-s in Condensing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it apperta ins to make and use the same.

This invention relates to condensers of that class known as fresh-water condensers, and it has for its object to provide a simple, effective, and inexpensive apparatus for household or domestic use in which a large condensingsurface is provided in a small compass; and it consists of the parts and combinations of parts hereinafter described and claimed.

In. the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of my improved apparatus; Fig. 2, a vertical longitudinal section through the same; Fig. 3, a perspective view of a modification of one of the condensing-chambers, and

Fig. at a section through the same.

Similarletters refer to similarparts throughout the several views.

A represents a metallic pipe of any desired diameter one end of which is suitably connected with a steam-generator (not shown) of any desired kind, the utensil known as a teakettle answering the purpose excellently.-

To the pipe A a pipe, B, is connected at right angles, and has its lower end fitted in a collar, a, which projects from the center of a supply-tube, C, said tube being closed at both ends, and having a series of lips, I), projecting from its underside at regular intervals apart from end to end of the tube, to which the short tubes 0, which project from the edges or peripheries of the disk-shaped condensing-chambers D, are connected. The chambers D are formed of circular concavo-convex plates of thin metal joined together at their edges in any suitable manner, with their concave faces toward each other, so as to form a condensingchamber between them whose greatest width is at the center, and which tapers gradually from the center to the peripheries of the plates. In Figs. 1 and 2 these plates are shown as perfectly smooth plane surfaces; but they may be corrugated from the center toward the edge or periphery, if desired, as shown in Figs. 3 and 4, in which the corrugations h are shown as deepest at the center of the plate and gradually decreasing in depth to near the periphery, where they terminate or merge in the metal of the plate.

In the lower edges of the chambers D opposite the tubes 0 tubes (Z are secured or formed, which enter lips or collars 01, formed on the upper side of a large receiving-tube, F, in which the water of condensation is received. This tube is closed at both ends and has a spigot, E, or other means for drawing oit the water provided. The tube F rests on a support formed with the semicircular collars 1), having perforated lugs r'formed thereon, in which the bent ends of legs 3 are inserted. To

the collars 19 side boards, I, which extenchqo along the tube F on each side and forirf a support for the chambers D, are riveted or otherwise secured.

The metal out of which the plates are made must be very thin in order to secure the best results, and therefore, if made perfectly fiat in the shape of disks and joined together at the edges, would not be strong enough to resist even slight pressure or blows accidentally or otherwise applied thereto, but would give to the pressure or blow and become bent, thus injuring and perhaps closing the free passage between the plates and ruining the apparatus. Therefore, in order to give the required strength without a corresponding thickening of the metal, I make the plates concave-convex, as described above, leaving, however, only a narroy or contracted passage be-' tween them which at its widest point is not over one and one-half inch. The corrugations in the plates are also very close together when the plates are brought together, so that at the widest point it will not be over the dimension named.

In operation the steam or vapor enters the pipes A and B, and from thence into the tubes (3, from which it escapes through the tubes 0 into the chambers D, where it is condensed by coming in contact with the plates forming the chambers, said plates being of thin metal,

- which quickly cools, and the water of condensation escaping from said chambers through tubes (1 into the receiving-tube F, from which it may be drawn by the spigot or other suitable means. Substantially the same operation takes place when the chambers shown in Figs. 3 and 4 are employed, the only reason for their employment being the greater cooling-surface they afford, owing to the plates forming the same being corrugated, as described.

Having thus described my invention, whatl claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a condensing apparatus, of the pipes A B, the tube 0, centrally connected with said pipe B and having a series of lips formed on one side thereof, the series of disk-shaped condensing-chambers formed of the concavo-convex plates joined municating with' said chambers, substantially as described.

In testimony whereof I affix mysignature in presence of two Witnesses.

JOHN F. CHASE.
